Outputting differences in arrays - c++

Question

I have to make a code where the user inputs altitude readings and the code is supposed to output total climb, total descent, and net change. This is what I have below. I can't figure out how to code to have it output what I want it to.
#include <iostream>
using namespace std;
int main()
{
int array[2010], n, c, d, swap; //the array
printf("Enter number of elements\n");
scanf("%d", &n);
printf("Enter %d integers\n", n);
for (c=0; c < n; c++)
scanf("%d", &array[c]);
for (c=0 ; c < ( n - 1 ); c++)
{
for (d = 0 ; d < n - c - 1; d++)
{
if (array[d] > array[d+1]) /* For decreasing order use < */
{
swap = array[d];
array[d] = array[d+1];
array[d+1] = swap;
}
}
}
printf("Sorted list in ascending order:\n"); //lists in order
for ( c = 0 ; c < n ; c++ )
printf("%d\n", array[c]);
// Returns minimum difference between any pair
int findMinDiff(int arr[2010], int n); //supposed to find differce
{
// Initialize difference as infinite
int diff = INT_MAX;
// Find the min diff by comparing difference
// of all possible pairs in given array
for (int d=0; d<n-1; d++)
for (int j=d+1; j<n; j++)
if (abs(array[d] - array[d--]) < diff)
diff = abs(array[d] - array[d--]);
cout<<"Total Climb "<<diff<<endl;
}
system("pause");
return 0;
}

I don't see why you are sorting the array. Sorting the array may cause problems in calculating the "total climb" and "total descent".
My understanding is that this assignment is about calculating the difference between two numbers and processing that difference.
void Process_Data(int array[2010], unsigned int quantity_of_climbs)
{
int total_climb = 0;
int total_descent = 0;
int minimum_change = INT_MAX;
for (int i = 0; i < quantity_of_climbs - 1; ++i)
{
const int height_change = array[i] - array[i+1];
if (height_change > 0) // A "climb"
{
total_climb += height_change;
}
if (height_change < 0) // A "descent"
{
total_descent = (-1) * height_change; // Change from negative to positive.
}
const int abs_height_change = abs(height_change);
if (abs_height_change < minimum_change)
{
minimum_change = abs_height_change;
}
}
// Display results
}
